One word of warning, purely hypothetical in nature. As of a couple of years ago, rumor had it that the guy who runs knjn.com (also fpga4fun.com) was convinced that his customers wouldn't mind running his proprietary .exe to configure the board's USB chip and FPGA every time the device boots up. Schematics were supposedly also not available at that time. If these rumored policies still prevail, that means you'll have to reverse-engineer the board's JTAG-over-USB connections in order to do anything practical with it. Oh, and also, if you propose open-sourcing the results of your reverse engineering effort, he may or may not throw a fit and accuse you of setting out to wreck his business model. Not that I have any direct knowledge along these lines. :-P Suggest going with a Digilent board instead -- the Nexys 2 is a bit more expensive but infinitely more 'hacker friendly' than any of the KNJN products. At the very least, you want to contact knjn.com before committing to their board and ask some very pointed questions about the development process and support code. -- john, KE5FX _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
